Vintage unique French foot warmer with tapestry

Vintage unique French foot warmer with tapestry fabric top 1930-50s Footed metal box with free moving handles and screw on lidded spout, stamped JMS, at side to fill with hot water. Can’t be opened and sounds like some kind of stones inside. I have only lightly dusted this piece and will leave it up to new owner to decide if further restoration is needed. In definitely well used condition with patina, but considering age, it is great! No major dents and tapestry is in really good condition. Cap unscrews freely also. Box is 9 3/4” long (11” including spout) x 7 3/4” wide x 3 1/2” high Smoke free, cat friendly home.
